After only two weeks of cocooning the moths are beginning to emerge. At the point of writing this I have two male moths with many more to come. Males are easy to identify because they have well formed wings and smaller bellies, they also hold their bottoms in the air and flutter their wings regularly to attract females (they make a sort of twerking motion with their bottoms too). At this point I am just trying to keep the remaining worms fed and find a place for the emerging moths, but I did find I couldn't resist processing just two of the now empty cocoons.

I got so excited that I didn't take photos, so words will have to do.
First I made sure the cocoons were empty by checking for the hole in the end. Then I heated some water on the stove in an old saucepan. I added a teaspoon of my home made laundry gel (more on this recipe at a later date) which is basically pure soap and washing soda with a few drops of eucalyptus oil. The teaspoon was more than enough for my two cocoons, I will add more cocoons to the next lot I process.
I let them simmer on the stove for half an hour (alongside the steaming veges for tea) then turned the heat off and let the water cool until I could reach in and scoop out the mass of silk. The two cocoons turned into a mass of tangled fibre in no time. Next I rinsed this mass under the tap until all the gel was removed and the yellow colouring had left the strands, I also picked out the left over skin and stuff from the cocoons at the same time. I haven't organised a frame to stretch the cocoons onto yet so I just spread the fibre out as best I could and left it on the sink drainer to dry.
When it was dry and a bit fluffy I took the opportunity to admire my first bit of peace silk fibre. Then I wacked the little mass on the carders and carded away for a few minutes until I had a passable rolag.

The whole silkworm story is fascinating; from the huge effect silk has had on world trade, politics and even exploration to the interesting fact that there are at least three genus of silk moth and not all of them eat mulberries and the many myths surrounding the discovery and production of silk.
Here is an interesting article about the effect silk had on world trade in history.
I am finding this journey of discovery very interesting; silk is an amazingly beautiful fibre and like all fibre sources it requires a bank of specialised skills and knowledge to produce. There is so much more left to learn. Once all my moths have emerged and lay eggs I will be experimenting with processing the cocoons, I might even try to unravel some hatched cocoons in the traditional manner and see why it's not considered to be viable.
